* ctcm: rename READ/WRITE defines to avoid redefinitionsUrsula Braun2010-08-125-110/+118
| | | | | | | | READ/WRITE seems to be a bit too generic for defines in a device driver. Just rename them to CTCM_READ/CTCM_WRITE to avoid warnings. Signed-off-by: Ursula Braun <ursula.braun@de.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| * [SCSI] zfcp: Trigger logging in the FCP channel on qdio error conditionsChristof Schmitt2010-07-284-4/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Exploit the cio siosl function to trigger logging in the FCP channel on qdio error conditions. Add a helper function in zfcp_qdio to ensure that tracing is only triggered once before calling qdio_shutdown. Trigger in zfcp for hardware logs are: - timeout for FSF requests to the FCP channel - "no recommendation" status from FCP channel - invalid FSF protocol status - stalled outbound queue - unknown request id on inbound queue - QDIO_ERROR_SLSB_STATE All of the above triggers run from the Linux qdio softirq context, so no additional synchronization is necessary for the handling of the ZFCP_STATUS_ADAPTER_SIOSL_ISSUED flag.

| | | | | | | | | | | | | | | | | | | | | | | | Configuring a LUN in zfcp, also creates a SCSI device. For consistency, it makes sense to remove the SCSI device when the LUN is deconfigured. Replace the flush_work with the call to scsi_remove_device: scsi_remove_device also takes the scan_mutex that synchronizes itself with any long running device discovery.

| | | | | | | | | | | | | | | | | | | | | | | | | | When running in non-NPIV mode, the port_reopen in terminate_rport_io might succeed even though the remote port is not available. If the same port connection is held open from another operating system, the reopen is only a virtual operation and might not hit the SAN.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the successful return of an adisc is the final step to set the port online, the registration of SCSI devices might be omitted. SCSI devices that have been removed before (due to a short dev_loss_tmo setting) might not be attached again. The problem is that the registration of SCSI devices is done only after erp has finished. The correct place would be after the call to fc_remote_port_add to mimick the scan in the FC transport class. Change the registration of SCSI devices to be triggered after the fc_remote_port_add call. For the initial inquiry command to succeed, the unit must also be open. If the unit reopen is still pending, the inquiry command to the LUN will be deferred with DID_IMM_RETRY, so there is no harm from this approach.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 64deb6efdc5504ce97b5c1c6f281fffbc150bd93 changed the way status read buffers are handled but forgot to adjust the mempool to the new size. Add the call to resize the mempool after the exchange config data. Also use the define instead of the hard coded number in the fsf callback for consistency.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Trying to read the FC host statistics on an offline adapter results in a 5 seconds wait. Reading the statistics tries to issue an exchange port data request which first waits up to 5 seconds for an entry in the request queue. Change the strategy for getting a free SBAL to exit when the queue is stopped. Reading the statistics will then fail without the wait.

* | | [S390] cio: fix potential overflow in chpid descriptorSebastian Ott2010-07-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The length filed in the chsc response block (if valid) has a value of n*(sizeof(chp_desc))+8 (for the response block header). When we memcopied from the response block to the actual descriptor we copied 8 bytes too much. The bug was not revealed since the descriptor is embedded in struct channel_path. Since we only write one descriptor at a time ignore the length value and use sizeof(*desc).
